APPARATUS FOR CHANGING WINDING-ROPES IN MINES.

SPECIFICATION forming part of Letters Patent No. 723,437, dated March 24, 1903.

Application filed February 14, 1902. Serial No. 94,103. (No model.)

To all whom it may concern.-

Be it known that I, ALEXANDER BEIEN, a subject of the German Emperor, residing at Horne, Westphalia, Germany, have invented certain new and useful Improvements in Apparatus for Changing Winding- Ropes in Mines, of which the following is a specification. v

This invention relates to an arrangement for placing the winding-rope in position, and particularly in the Koepe system of winding for mines.

In changing or replacinga winding-rope in the Koepe system of winding an ordinary steam-crane has heretofore been employed, in which operation the new winding-rope is previously wound on the dru m of the steamcrane and then allowed to descend into the shaft, at the same time reversing the engine and applying the brake. the disadvantage that the new winding-rope is crushed and rubbed on the'drum of the steam-crane and is therefore already damaged before it is used, especially when the Weight of the rope suspended in the shaft is very great. Detrimental action on the winding-rope would certainly not take place on an ordinary steam-crane drum if there were sufficient room to wind the rope with the convolutions arranged side by side. In that case, however, if, for example, one thousand meters of rope of sixty millimeters diameter were to be wound on a drum with the convolutions arranged side by side the drum would have to be of colossal dimensions,which is quite out of the question in practice. One is here always obliged to wind the rope in a number of layers arranged one over another. The

winding of a thick rope of this kind on av steam-crane drum, which has usually a diameter of about one motor, can, however, only be done loosely without mechanical means by reason of the stiffness of the rope. With mechanical means the rope would be damaged, since the projecting yarns would exert an excessive pressure on each other at the places of contact of the several convolutions. If now the rope under greater tension-that is to say, with the weight of the rope in the shaftsuspended therefromis unwound from the drum, the remaining convolutions draw themselves tighter on the drum, and since This method has the rope was wound on loosely the inner hemp core will consequently be deformed and pressed fiat or into rectangular form. By this means sliding apart of the projecting wires takes place and crushing or rubbing sets in. In order to obviate this disadvantage, according to the'said invention instead of the ordinary steam-crane a friction-geared steam-crane, with two drums and a winding reel or winch belonging thereto, is employed.

In the drawings, Figure 1 is aside elevation of a winding system for mines, showing the manner of utilizing my invention, the mineshaft being in section; and Fig. 2 is a plan view.

In this arrangement the new rope m, which is in the first place WOtllldOIllO the Winding reel or winch a, is passed several times around the drums of the friction-geared crane b and thereupon passes over a roller or rope-wheel c and is spliced to the old rope y, as indicated at z, the old rope having been disconnected from the upper cage h, which is temporarily supported in any suitable manner. The old rope y is also disconnected from the lower cage k, which may rest upon the bottom of the shaft or be otherwise suitably supported and connected to a reel or winch g to be wound thereon. When the rope is passed several times around the drums of the friction-geared crane b, the tension of the rope between the winch a, and the said drums b will be very small compared with that between the drums b and the ropewheel 0, and therefore the rope will not be damaged on the winding reel or winch. The drums of the friction geared crane Z) are preferably provided with half-round grooves, and the rope is guided by these grooves in convolutions lying side by side without these convolutions touching each other. 1 On the winding reel or winch a, there is certainly a drawing together or tightening of the convolutions of the rope; but the tension between the winding reel or winch and the frictiondrums does not amount to the one one-hundred-and-fiftieth part of the tension beyond the friction-drums and can thus scarcely come into consideration.

The placing of the winding-rope in position on the driving-wheel is effected by means of the new arrangementfor example, when replacing an old cable by a new one-as follows:

ICO

As shown clearly in Fig. 1, the old rope 1 passes from the splice .2 over a rope-wheel d, around a driving-wheel 6, over a rope-wheel f, down the shaft to the reel or winch g. If now the friction-geared steam-crane and likewise the driving-wheel e of the winding-engine are set in motion, the new rope passes over the first rope-wheel cl at the head of the shaft, the driving-wheel e, and the second rope-wheelfat the head of the shaft gradually into the place of the old rope and is afterward connected up, the old rope having been wound up during the process on the winding reel or winch What I claim is- 1. In an apparatus for changing ropes in mines, the combination of a winding-reel a upon which the substitute rope is wound, a friction-geared steam-crane I) provided with two drums around which the substitute rope passes from the reel a, in single convolutions side by side, and a rope-wheel 0 under which the substitute rope passes to be temporarily connected to the rope to be replaced, substantially as set forth.

2. In an apparatus for changing ropes in mines, the combination of a winding-reel (it upon which the substitute rope is wound, a friction-geared steam-crane 12 provided with two drums around which the substitute rope passes from the reel a in single convolutions side by side, a rope-wheel 0 under which the substitute rope passes to be temporarily connected to the rope to be replaced, a. drivingwheel e and rope-wheels d, f, for driving and guiding the ropes, and a reel 9 upon which the rope to be replaced is wound, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of two witnesses.
